WILLIAM SEVERNS, 0F CHICAGO, ILLINOIS;

MOP-CUTTING MACHINE.

Application filed August 17, 1921. Serial No. 493,013.

To all whom t may camera:

Be it known that I, WILLIAM SEvERNs, a citizen of the UnitedStates, anda resident of the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in a Mop-Cutting Machine; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had totheaccompanying drawings, and to the numerals of reference marked thereon,which form a part of'this specification.

This invention relates to improvements in machines for making mops andis especially adapted for use in connection with the .manufacture of amop and the process of cation herein referred to, but it will beunderstood that it is adapted to be used with other machines for makingmops or the like and is not confined tothe particular process asdisclosed in the copending application.

One of the objects of this invention is the provision of a machineadapted t0 properly sever the strands 0f a skein of hank or yarn or thelike which has been wound upon a frame in regular order and which willsever this yarn in such a manner as to form it into strands of equallength to constitute the body of a mop. .Another object of thisinvention is the provision of a machine which has cutting knives adaptedto sever such a skein or hank of yarn into strands of equal lengthl toform a mop, a cutting knife being mounted upon each side of the machineand both coacting together to complete the cutting of the' strands inone operation of the machine.

Still another important object of the invention is the provision of amachine adapted to cut yarns intoy lengths to form mops which is adaptedto be used with a frame upon which the yarn is wound and 'which isadjustable so that the knives may be adjusted to conform to anyparticular size of frame adapted to make any size or weight of mop asrequired, Y

illustrated in the drawings and hereafterVA more fully described.

0n the drawings:

Figure 1 is a top plan view of the machine as embodied in this inventionFigure 2 is a sectional view taken on line 2 2 of Figure 1, looking inthe direction indicated by the arrows.

Figure 3 is a plan View of the frame upon whlch the strand of yarn iswound preliminarily to forming the mop.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is an enlarged detail View showing the construction of one ofthe rotary'A gutting knives ,and the driving means there- Figure 6 is asimilar .View of one of the rotary cutting knives showing the means bywhlch 1ts position relative to the machine and to the other knife isadjusted.

As shown on the drawings:

T he machine comprises a frame or base 10 having supporting legs 12 andprovided at 1ts top with a table or platform 14 upon which the work isplaced to be operated upon. Mounted upon a shaft 16 extendingtransversely of the machine are'a pair of pulleys 1 7 and 19, one fordriving and the other a loose or idler pulley connected by a belt -toany convenient' source of power. Slidably mounted on the shaft 16 andkeyed by suitable keys or feathers acting in the keyway 21 so as to berotatable therewith is a beveled gear 18 mounted in bearings integralwith and projecting from a downwardly extending support 20 which is heldin position by the table 14 and the shaft 16. A similar support 50 isprovided for a gear 38 likewise fixed on and driven by the with and bedriven by the beveled gears 18 and 38 on-the shaft 16. Integral with thesupporting member 20 is an outwardly eX- tending 'lug 30 having a holetherethrough, as shown in Figure 5, and this lhole is internallythreaded to correspond with'threads on an adjusting rod 32 extendingtransversely of the machine, and having its ends mountedin bearings inthe frame, as shown in Figure 2. This rod 32 is provided with right-handthreads on one side thereof and, 1f desired, left-hand threads on theother side so that the rotation thereof by means of a wheel or handle 34will tend to cause the approach or recedence of one or both of themembers 20 and '50 to and from each A other, this movement of courseincluding their attached gears 18 and 38 and the circular knives26ldriven thereby. Adapted to co-operate with the circular knives 26 isa frame 40 upon which a strand of yarn is woundin regular layers to forma mop, the process o f winding this yarn and forming a mop beingdescribed in my co-pending ap plication hereinbefore referred to.

A strip or support 42 is sewed to the strands of yarn after they havebeen wound on the frame 40, as best shown in'Figure 3, and the framewith the yarn thereon is then passed' through the machine and thecircular knives 16 act to sever the yarn at both sides of the frame,suitable depressions or grooves being provided in the frame, as

shown at 44 in Figure 4, to provide for the edges'of the knives andtheir proper coaction with the frame 40. In this way the yarn on theframe is severed in a neat, quick and eiicient manner and the edges arecut so as to correspond very closely to each other when the swatch soformed is folded over to form the finished mop.

The frame 40 may be fed through the machine either by hand or with a.manually regulated mechanical feed if desired, or the feed may beentirely automatic, depending upon the nature of the operation.

The operation is as follows:

After the yarn 41 has been wound upon the frame 40 by any suitable means(the preferred form being shown in my copending application for U. S.Letters Patent on machine for making mops, filed August 17th, 1921,Serial No. 493,014, and the strip or binder 42 sewed thereon, the framewith the attached yarn is then in the condition as mop. The swatch isthen doubled into the form' of a mop, as shown in my copendingapplication hereinbefore referred to.

It will be evident that the frames 40 may be made of any size for theconstruction of mops of -any desired weight or size, and that the`construction of these frames allowing the mechanical winding thereon ofa sufficient quantity of yarn is a much more eiiicient operation thanthat formerly in use whereby an approximate quantity of yarn was takenby hand from a stack of the same, weighed upon a scale and then manuallydistributed over a strip to which it was afterwards sewed. In the sewingthe edges were always left uneven and the product had to be cut andtrimmed with a resulting loss of material.' All of these operationsbeing manual consequently involved an expenditure of a good deal of timeand expense, and also considerable waste.

The operation of this machine will tend to form a mop'y in a muchshorter space of time than has hitherto been required and consequentlywill turn out a much cheaper product and one which is cut more neatlyand therefore --more eiiicient in its operation, inasmuch asW the lengthof all the strands is exactly the same.

I am aware that many changes may be made and numerous details ofconstruction varied without departing from the principles of thisinvention, land I therefore do not purpose limiting the patent grantedhereon otherwise than necessitated by the prior art.

I claim as my invention:

1. In apparatus for making mops, a frame having parallel grooved sidesupon which the yarn is wound, in combination with spaced rotary cuttingelements between which the frame is passed with the grooved sidesadjacent the cutting elements.

2. In apparatus for making mops, a frame having parallel grooved sidesupon which the yarn is wound, in combination with adjustably spacedcutting elements between which the frame is passed with the groovedsides adjacent the cutting elements, and means for simultaneouslyrotating said cutting elements.

3. In apparatus for making mops, a support, a pair of spaced rotarycuttingelements mounted in said support, means for relatively adjustingsaid cutting elements, a In testimony whereof I have hereunto subcornmondrive shaft geared to both cutting scribed my name in the presence oftwo subelements, in combination with a frame havscrlbing witnesses:
